SECTIONAL METALLIC BARREL.

Specification of Letters Patent.

Patented Mar. 5, 1918.

Application filed March as, 1916. Serial No. 87,351.

To all whom it may concern:

Be it known that l, JOHN W. DARLEY, Jr., a citizen of the United States, residing at Baltimore, in the county of Baltimore and State of Maryland, have invented certain new and useful Improvements in Sectional Metallic Barrels; and I do hereby declare the following to be a full. clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

My invention relates to metallic barrels, and the object of my invention is to produce a metallic barrel, which shall be light. strong of a bilged form and which shall be so constructed that the head can be readily removed when access to the interior is desired.

A further object of my invention is to i provide a barrel which can be readily knocked down when the barrel is to be re shipped for reuse as a container.

This present application for United States Letters Patent relates only to the construction of the staves and hoops of my improved barrel.

In the drawings Figure 1, is a perspective view of my improved barrel;

Fig. 2, is a partial. longitudinal section of my improved barrel along the line 2-2 of Fig. 1;

Fig. 8, is a transverse section along the line 33 of Fig. 1;

Fig. 1 is a perspective view of one stave;

Fig. 5 is a perspective view of one head; and

Fig. 6 is a perspective view of the chine ring.

la the drawings 16* represents a stave of which there may be any suitable number used in the barrel, there being 8 staves in the barrel shown.

Each stave on its outer surface is provided with a plurality of corrugations 11, extending from its outer surface inwardly.

Corrugations 11 are substantially semicircular in cross section and are provided with rounded ends. There may be any desired number of corrugations employed but they should extend inwardly from the outer surface of the staves as shown in order to insure an approximately smooth surface for the barrel to roll upon.

The corrugations 11 do not extend across the full width of the staves, but smooth borders 12-12 are provided between the ends of said corrugations and the edges of said staves.

Each stave along one edge is provided with a rib 13 projecting radially inward, and the inner edge of said rib is substantially straight as shown at 1 1 Fig. 4.

On the other edge of each stave there is provided a ribbed portion 15 which projects radially inward and has formed in tegrally on its inner edge, a curved flange 16. The flange 16 is substantially straight longitudinally but its outer edge is curved as shown at 17 in Fig. 1.

The rib 13 and the rib formed of the straight portion 15, and the curved flange 16 are of the same length and extend between the inner surfaces of the heads 18 as shown in Fig. 2. p

The edge 1 1 and the portion 16 are formed substantially straight longitudinally so as to give the rib 15 and the rib formed of the portions 15 and 16 greater radial widths at the largest part of the bilge of the barrel than said ribs have at the ends. By this means said ribs are made very much stronger and the barrel is rendered more able to resist stress applied to the bilge thereof. The ends of said ribs form the inner supports for the heads 18.

The ends of the staves are provided with portions 19-19 which are curved to fit the cylindrical surface of the flange 21 of the head 22, shown in Fig. 5.

The portions 19 extend as at 23 24: beyond the rib 13 and the rib formed by the portions and 16. On the outer ends of the portions 19-19, the flanges 25 are bent over as shown in Fig. 4. The flanges 25 are of lengths circumferentially about equal to half of the circumferential distance between the outer surface of the rib 13 and the outer surface of the portion 15.

A tab such as 26 is provided on one end of each of the flanges 25 and the ends of said tabs 26 are bent into slots cut into the portions 19.

The flange on both ends of each stave are similar and similarly situated, but the tabs 26 are placed diagonally opposite on the ends of the flanges as shown in Fig. 4.

The head 22 of my improved barrel is formed with the cruciform strengthening rib 27 having depressions 28 between the arms thereof, and a circular strengthening rib 29 connecting said arms.

The flat annular portion 30 extends radially outward from the strengthening rib 29 to the cylindrical flange 21. The cylindrical flange 21 has eight cut away portions 31 for a purpose hereinafter explained. 1 Between the cut away portions 31, there are thus left eight full width portions such as 33.

The circumferential length of each portion 33 is slightly less than the circumferential length of the cut away portion 3i.

There are as many portions 33- and as many cut away portions 31 as there are staves in'the barrel.

The chine ring for my improved barrel is substantially til-shaped in cross section,-- being provided with an inner portion 34k, a top. portion 35, an outer portion 36 and an apron 37, having a plurality of depressions 38 equal in number to the number of staves in the barrel.

The head and chine ring, shown respectively in Figs. 5 and 6, forming the subject of applications for United States Letters Patent filed on even date herewith will not be further illustrated. or described.

The process of assembling iny improved barrel is as f0llows';-

'The ribl3 of one stave is introduced into the opening between the portion 15 and 16 of the flanged rib of the ndzrt adja cent stave and the process is repeated with adjacent stares until a sufficient number of staves have been thus assembled to form the body portion of the barrel.

During the process of joining the staves together it is evident that the ribs 13 must be passed between the portions 2l--2 l-, and that the portions 28-23 will overlie the pertions 2d-2 l, hence, it is'evident that the portions 24lbearing against the ends of the rib l3 will prevent longitudinal displacement of one stave with reference to another, and the portion 23 hearing against the portion will additional strength the chine within the portions 19 in such a location that the portions 38 of the flange 21 will be between the flanges 25 on the ends of the portions 19. The head is then driven inwardl until its inner surface rests against the ri s 13 and the rib portions 15. The head is then to be turned slightly in a clockwise direction to bring the portions'33 under the flanges 25, which are substantially U- shaped in cross section, in order to lock the head 22 with the stares 10.

The chine ring shown in Fig. 6, is then driven over the flange of the head and the ends of the staves in such a location that the depression 38 will spring into the end corrugations 89 of the stares 10, thus completing the assembling of the barrel. 1

When the barrel is to be opened, by applying a swedge to the straight portions to of the apron 37, the chine rings can be driven upwardly and off from the barrel. The head 22 is then to be revolved in a counter cloclrwise direction until the portions 33 pass from under the flanges 25, and this movement the head is to be continued until the stave portions Ell strike the tab 36on the end of the neat adjacent flange 25, thus forcing the corresponding stave outwardly and the continued motion of the head, brings each portion in line with a flange 25 so that the head 22 can be readily removed I claim A stave for a metallic barrel having a body portion provided with ribs, curved end portions each provided with a slot, a flange on each end portion, and a tab on each flange bent into said slot,
